摘要： Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

摘要： Techniques are described for providing a-priori information about the implication of a network device operator interaction with a network device, e.g., a software configuration or hardware change, to be performed on the network device before the interaction actually takes place. The network device operator is provided with information that may be used to make a decision whether to proceed with the interaction. For each logically distinct feature of a network device, the techniques generate a trigger outcome domain (TOD). Each TOD is defined to include a list of operator interactions that defines relevant events in the network device that may be triggerable by the operator interactions, a list of potential outcomes in the network based on the potential events in the network device, and a user interface to display the list of potential outcomes for the operator interactions prior to performing any of the interactions.

摘要： Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals and desiring to transmit traffic signals to the two access terminals in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., identifying partition portion assignments, data rate and/or coding information, is also communicated in the traffic segment as in-band control signaling. An access terminal, to which some of traffic signals are directed, receives and recovers the in-band control signaling, identifying its allocated partition portion of the traffic segment and identifying data rate and/or coding information used. The access terminal receives the traffic segment signals in its allocated partition portion and recovers the traffic information.

摘要： A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations a wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

摘要： Systems and methodologies are described that facilitate detecting impulsive interference of pilot signals in wireless communications networks and accounting for such interference in estimating data channels to decode the pilot signals. Portions of a received pilot signal can be compared to other portions to create correlated subsets of similar portions. The number of portions in a subset can indicate a high likelihood of non-interference, and portions that are not in the subsets can be disregarded or weighted less in estimating channels for decoding. In cases of ambiguous subsets or portions, one or more subsets/portions can each be used to estimate the channel and data can be decoded multiple times. The decoding that results in a higher decoding metric can be selected. Additionally, systems and methodologies for inserting pilot signals within data are described.

摘要： An adaptable decision parameter is used to determine whether to react to resource utilization messages. The decision parameter may comprise a decision threshold that is adapted based on received resource utilization messages. The decision parameter may comprise a probability that is used to determine whether to react to a received resource utilization message. Such a probability may be based on, for example, one or more channel conditions, the number of interferers seen by a node, the number of received resource utilization messages, or some other form of resource utilization message-related information.
